Heart Failure Occurrence: Mining Significant Patterns and 10 Days Early Prediction
2021
Electronic health records containing patient’s medical history, drug prescription, vital signs measurements, and many more parameters, are being frequently extracted and stored as unused raw data. On the other hand, machine learning and data mining techniques are becoming popular in the medical field, providing the ability to extract knowledge and valuable information from electronic health records along with accurately predicting future disease occurrence. This chapter presents a study on medical data containing vital signs recorded over the course of some years, for real patients suffering from heart failure. The first significant patterns that come along with heart failure occurrence are…
Towards visual urban scene understanding for autonomous vehicle path tracking using GPS positioning data.
2019
This PhD thesis focuses on developing a path tracking approach based on visual perception and localization in urban environments. The proposed approach comprises two systems. The first one concerns environment perception. This task is carried out using deep learning techniques to automatically extract 2D visual features and use them to learn in order to distinguish the different objects in the driving scenarios. Three deep learning techniques are adopted: semantic segmentation to assign each image pixel to a class, instance segmentation to identify separated instances of the same class and, image classification to further recognize the specific labels of the instances. Here our system segme…
Vers le développement d'un capteur photoplétysmographique sans contact
2019
Heart-rate estimation performed with remote photoplethysmography is a very active research field. Since pioneer works in 2010, which demonstrated the feasibility of the measure with low-grade consumers’ camera (webcam), the number of scientific publications have increased significantly in the domain. Hence, we observe a multiplication of the methods in order to retrieve the photoplethysmographic signal which has led to an increased precision and quality of the heart-rate estimation. Region of interest segmentation is a key step of the processing pipeline in order to maximize the quality of the measured signal. We propose a new method to perform remote photoplethysmographic measurement using…
La laïcité, une identité française ?
2016
What should be the right place for religions in France ? Our debates are old and sharp. France has two legislations : a concordat (Napoléon) for two departments and the common rule (1905). The word "Laîcité" was not employed at the beginning, but appears progressively. Do Muslims living in France are changing the concept ? Do they imply a new manner of seeing things ? What are the results of the attacks of 2015 and 2016 on the opinion ? We analyse in this communication for the universities of Bucharest and Craiova articles published in the newspaper Le Monde. What is the reflection about the concept of "laïcité", what are the traditional arguments and the new ones ?
Hugh MacDiarmid’s Typescript ‘Hugh MacDiarmid and the Scottish Landscape, by Valda Trevlyn’ : Landscape as Sign
2013
International audience; In a 1911 letter, the young Hugh MacDiarmid told his professor, George Ogilvie, of his love of mountaineering: “I am constantly crossing mountains, by unutterably rocky tracks”, foretelling his life-long fascination for the Scottish landscape. MacDiarmid’s nationalist use of the Scottish scenery has already been much commented upon. However, we would like to introduce an unpublished typescript entitled “Hugh MacDiarmid and the Scottish Landscape, by Valda Trevlyn” . The text was undoubtedly written by MacDiarmid himself, not by his wife, Valda, in 1939. Projected as “a study of the descriptive elements” of his “vision of Scotland”, this chaotic prose work mostly cons…
Electrophysiological evidence for the effectiveness of images versus text in warnings
2023
AbstractWarning sign plays an important role in risk avoidance. Many studies have found that images are better warnings than text, while others have revealed flaws of image-only warning signs. To better understand the factors underlying the effectiveness of different types of warning signs (image only, text only, or image and text), this study adopted event-related potential technology to explore the differences at the neurocognitive level using the oddball paradigm and the Go/No-go paradigm. Together, the behavioral and electroencephalogram results showed that text-only warnings had the lowest effectiveness, but there was little difference between the image-only and image-and-text warnings…
Revista electrónica de investigación y evaluación educativa
2014
Resumen basado en el de la publicación Título, resumen y palabras clave en inglés y español El lenguaje de signos es uno de los medios de comunicación utilizado por personas sordas. Se realiza un análisis cualitativo sobre el uso de metáforas en el lenguaje de signos de un grupo de personas adultas sordas de la Comunidad de Sordos de Chile. Se identifican metáforas gestuales de variada índole y se analizan las posibles relaciones entre estas y las metáforas del lenguaje oral en Chile. Por último se comentan las posibles implicaciones de los resultados para la educación de sordos y la relevancia de éste en la evaluación de las habilidades cognitivas y lingüísticas de esta población. Valencia…
Many witnesses, many layers: the digital scholarly edition of the Iudicium coci et pistoris (Anth. Lat. 199 Riese)
2014
Il progetto di ricerca messo in cantiere durante l'anno della mia borsa di studio post-doc presso il Centro Linceo Interdisciplinare “B. Segre” dell'Accademia dei Lincei prevede la creazione di un'edizione critica digitale del Iudicium coci et pistoris iudice Vulcano di Vespa (Anth. Lat. 199 Riese), un testo latino tardoantico in versi con una tradizione pluritestimoniale. Tale edizione intende mettere a frutto gli apporti della semiotica, della linguistica e di quella sua parte detta grafologia, applicando le intuizioni teoriche e metodologiche di Tito Orlandi (vd. in particolare Informatica testuale, Laterza: Roma 2010); ed applicare, innovandolo, il markup XML/TEI. In tale edizione, le f…
Contribution of benzodiazepines in dental care of patients with special needs.
2019
Background Conscious sedation in dental treatment of patients with special needs (PNEs) has the purpose of controlling events such as anxiety and fear, as well as promoting muscle relaxation and mastery of uncoordinated movements. Benzodiazepines (BZDs) are among the most used drugs due to their anxiolytic, hypnotic and sedative properties. The objective of this investigation is to demonstrate a study on the contribution of conscious sedation with BZD in PNEs. Material and Methods The study included 40 PNEs, non-collaborators, submitted to conscious oral sedation with Midazolam (0.5 mg/kg) for dental treatment, receiving vital signs monitoring in the pre, trans and postoperative periods. Re…
Orthostatic hypotension and health outcomes: an umbrella review of observational studies
2019
To investigate potential relationships between orthostatic hypotension (OH) and negative health outcomes and mortality, through an umbrella review with integrated meta-analyses. Orthostatic hypotension is significantly associated with several negative outcomes in older people, but a suggestive evidence is available only for higher risk of coronary heart disease congestive heart failure, stroke, falls dementia, and all-cause mortality. Orthostatic hypotension seems to be significantly associated with several negative health outcomes in older people, even if only associations with coronary heart disease, congestive heart failure, stroke, falls, dementia, and all-cause mortality are supported …
